In this experiment students calculate the density of water and ice. Teachers may want to review some concepts of mass, volume, and density before beginning. Key questions include: What happened to the mass of the ice after it turned to water? Why? What happened to the volume of the ice after it turned to water? How do your results compare with those in the scientific literature? (author/kct)

This is a good site for an instructor teaching in the Construction Technologies career field pathway for air conditioning, heating, and refrigeration. It has practical demonstrations of ice and its properties which will assist students in understanding the nature of heat loss and heat retention.
